Das Boot! - Replace if tightening clamps does not work, also check header tightness to head. GT - JBOTDS! EZ  | ||

OK I feel the fool....I had assumed that because my boot couldn't move (metal collar) that it wasn't broken. Back to the drawing board. | ||

What is the worst thing that could happen if you use too small a jet after installing the pro-series exhaust and intake? I have both and the stock jet 1.70, seems to work a little better than the next size up, 1.75. I ask if this will destroy my motor, because my boat motor has been destroyed, according to mercury, by running too lean. Of course, it is a two-stroke, lubricated by oil in the fuel. | ||

Both jets work. It is unlikely that you will burn your engine up being one jet size off (assuming the 170 is too lean). The jet sizes here are guidelines (as are any with a pre packaged jetting kit) and should get you close. It really should be tuned by a qualified mechanic. But realistically, its highly unlikely you'll destroy your engine, but it is possible. Richer jetting is usually safer (too lean & you fry the engine quickly-too rich and you accelerate engine wear). | ||

12.0 to 1 fuel/air ratio is what you want !!! The engine will run better and if you stay off the throttle it will not hurt your gas mileage ... In BLASTing LaFayette | ||

Thanks, guys. I appreciate the opinions. Just want to keep the Blast alive for as long as possible. It shouldn't hurt the bike to use the larger jet, so I think I will give it another chance. How's about two tanks of gas worth? If it totally ruins my gas milage, I will switch back. Maybe I should find out how much to run a test on Dyno with some kind of gas sniffer to tell me if the fuel-air mix is correct? | ||

It's getting pretty common for dynos to have the air/fuel ratio thing. If you're calling local places to check rates, just ask if it has "air fuel". | ||
| Jmynes |
Or you could take a gander at the spark plug. Waaaaay cheaper to do than dyno runs. | ||
| Buellboy492 |
What does a dyno run cost? Have never asked. Of course, I will have to go incognito around here. Motorcycle racisim, you know what I mean? I feel like a second class citizen just because I don't want to spend $15,000 on a "wooly mammoth with tassles". The Blast has an image problem with the lifestyle bikers around here. But a Harley riding fella showed some understanding last weekend. He asked how many miles did I have and how long I had it. When I told him, he goes, "Oh. You're pretty happy with it then, huh? Cool."  | ||

I've paid $42 - $125 depending on time spent. The HD only dealers I've talked to wouldnt touch the Blast. | ||
| Ezblast |
Tried Turbotimes boot - thanks Jim - it tore - will try the second one with stock clamps instead of the heavy duty puppies I paid some bucks for - lol GT - JBOTDS! EZ | ||
| Gearheaderiko |
Have we (you) tried the green stripe hose they sell for dirt trackers? It always seems to come down to the stock boot and clamps being best!~ | ||
| Ezblast |
Got a Makers name - stock # or something to reference it to a shop for ordering? GT - JBOTDS! EZ | ||
| Xgecko |
yeah I'm back to a stock boot. the metal reinforced boot tore under the metal and the all rubber ones I tried wouldn't stay seated (though they were stronger). Dirt track stuff could be and option. BTW I now carry a spare boot just like the rest of the long term blasterds (Message edited by xgecko on July 09, 2006) (Message edited by xgecko on July 09, 2006) | ||

Storz Performance. Gates Green Strip hose. PT# 24224 or 24226 but I'm sure its available elsewhere in different sizes. www.Storzperf.com but always see if the Badweb sponsors carry it first! | ||
| Ezblast |
Thank you Erik - I will also try this - S118571X and the hydraulic hose is 1-3/4" I.D. and it cost all of $8.76 for one foot of it - had the #'s on a foot of it - SAE 20 R1 SB/SC 2 - will try for an equivalent hydrolic hose - And was bought at a local Case/IH dealer. - Please remember - I will be using Breezes Heavy Duty Band Clamps with hose protectors - they are wider, do not back out and can be torqued to high tension so there is no slipage.

Hey all, been a long time! I sadly, didn't have the blast on the road last year, and after pulling it out of storage, it seems to be running great, with few problems. I have the pro series intake, V&H exhaust, re-jetted carb. My acceleration is great (aside form the flat spot in the middle), except when I twist the grip more than 3/4. At that point the bike seems to suffer a loss in power (compared to power in the rest of the twist). I'm wondering if anyone has any ideas as to why this is happening. Aside form this, the bike is running the best it ever has. Thanks | ||
| Swampy |
clean the main jet on the carburetor, it is probably sludged up and restricting flow. | ||
| Gearheaderiko |
Besides checking the main jet I just want to be sure you've run through at least one tank of gas. Old gas will also do that. | ||
| Swampy |
How true! Tank of gas is much easier! Has anyone tried the Scary Fast, Power Now? It fits inside the carb venturi and directs air for better idle-midrange. | ||
| Snotires |
yeah, I changed the gas before I started it up. This problem isn't new, It just seems worse. I'll get on the main jet, thanks guys. | ||
| Ezblast |
Hmmm - interesting - http://scaryfastracing.net/harley.html Will study further - have questions on how well it will work with the Black bikes Dial-A-Jet, however, perhaps the red - hmmm - would like to hear some cons to the system. GT - JBOTDS! EZ | ||

I'm always skeptical. CV carbs have been around a LONG time and this is way to simple a concept to have just been "invented" now. If it worked - it should have been designed into every carb since the 1960s. Would love to be proven wrong. nick | ||
| Swampy |
The problem I am trying to correct is the off idle bog or flat spot. If you crack the throttle open quickly off idle, the engine will hesitate and you can see lots of intake gasses regurgitating back out of the carb until the RPM's pick up. I have held a long stack on the carb and it goes away, I don't know what happens to the the top end power, but the bottom end sure seems to improve. I then held a small piece of aluminum flashing cut to taper into the venturi about 1/3 above the bottom of the venturi opening and it goes away also. I truely believe that a longer intake track will improve the bottom end on these engines. There must be an engineering formula to make that determination. You see longer intake tracks and velocity stacks on the exotic road racing engines on cars, and short ones on the drag cars. | ||
| Gearheaderiko |
Have you tried a velocity stack from American Sportbike ? (it might even fit inside the stock airbox, but its been so long since I've seen a stock airbox, I dont remember).Are you using Pro Series or stock? More than likely any lengthening wont hurt the top end. PS Do you have a parts manual for a Sportster? | ||
| Swampy |
Nothing will fit in the stock air box but air....I tried a 3/4" aircleaner spacer and the stock velocity stack(about 1/2") and it was too much to fit under the cover. And no I don't have a Sportster Parts book. | ||
| Gearheaderiko |
Have you tried running it with the spacer,stack and no air filter to see if the hesitation goes away? I dont think a longer intake will help bottom end as much as maybe a narrower intake, but I cant argue with your testing. Have you tried a Pro Series intake? | ||
| Xgecko |
or a Ray Series intake? you could build one how you want it then (Message edited by xgecko on July 14, 2006) | ||
| Naustin |
Off topic, but is it possible to flip the intake manifold over so it curves to the left side of the bike instead of the right, relocate the carb basically to the center-line of the bike, and then build a custom intake that takes advantage of the extra space to avoid interference with the rider's knee? | ||
| Ezblast |
Good question! |
